Found this tidbit on a website :
" Vincent Kennedy McMahon was born on August 24, 1945 in Pinehurst, North Carolina to parents Vincent McMahon Sn and Vickie McMahon. Vince, who some would say was a problem child, was brought up by his mother, a goverment secretary, and a series of stepfathers in an 8 foot wide trailer in Havelock, North Carolina. In a Playboy interview Vince gave, he admitted he was physically abused by one of his stepfather's and sexually abused by his mother. As a child, Vince suffered from dyslexia. At the age of 12, Vince met his father, Vince McMahon Sn for the first time. After getting into trouble numourous times with the police Vince was sent to Fishburne Military School in Waynesboro, Virgina and was the first cadet in the School's history to be court-martialed."
So I was right about him showing signs of a person sexually abused & physically abused as a child.
I guess that explains where it came from. Vince has always seemed miserable & bitter. Now we know why.
